mac电脑，eclipse设置jdk_home

Use the

/usr/libexec/java_home

utility which returns the path to the preferred JVM version.
With

/usr/libexec/java_home -V

you can retrieve a list of all installed JVMs.

The easiest way to set up

$JAVA_HOME

is:

export JAVA_HOME=$(/usr/libexec/java_home)

This will always set the path to the latest JVM, so you don't have to update it after upgrading java.
